San Francisco’s police chief confirmed in an interview Friday that one of the two teenage girls killed in the crash of a passenger jet at SFO was run over by an fire truck while she was hidden by foam sprayed by firefighters to extinguish the flaming wreckage.

Emergency calls from people aboard a plane that crashed at San Francisco International Airport portray a scene of chaos, with passengers begging for help and saying ambulances weren’t coming fast enough.

The cabin manager of an Asiana Airlines flight that crashed over the weekend said she and the crew are working as hard as possible to recover. She was flanked by five other crew members, one of whom was in a wheelchair. Some of them had their heads bowed.

Investigators trying to piece together what went wrong will consider a report about a blinding light flash and the pairing of the pilots, who were assigned to work together through a tightly regulated system developed after several deadly crashes in the 1980s were blamed in part on inexperience in the cockpit.

Investigators are trying to understand whether automated cockpit equipment Asiana flight 214’s pilots said they were relying on to control the airliner’s speed may have contributed to the plane’s dangerously low and slow approach just before it crashed.
